Depending on the cultivar that you selected, it may not be fully hardy in your area. This is the lowest climate zone,7, that some varieties can handle, and some will even not perform well here.
If you believe that you have a hardy variety, then the next issue that we need to look at is fertilization. It isn't necessary every year, but doing so every spring will boost your results.
You should also trim this back to 5 or 6 inches from the ground each spring right at the new growth starts to show. This will help the new grass be a little thinner, and help it to flower properly.
